| Before |
3 u - $2.70 |
1 u + $2.70 |

| After |
3 u |
1 u |
Gabriel had $3.80 less than Tim. If another $3.80 was given to Gabriel, Tim and Gabriel would have the same amount at first.
3 u - 2.70 = 1 u + 2.70 + 3.80
3 u - 1 u = 2.70 + 3.80 + 2.70
2 u = 9.20
1 u = 9.20 ÷ 2 = 4.60
Amount that Tim had at first
= 3 u - 2.70
= 3 x 4.60 + 2.70
= 13.80 + 2.70
= $16.50
Answer(s): $16.50
